Q3) Researchers randomly assigned 72 chronic users of cocaine into three groups: desipramine (antidepressant), lithium (standard treatment for cocaine) and placebo. Results of the study are summarized below.
1- What is the probability that a patient relapsed?
2- What is the probability that a patient received the antidepressant (desipramine) and relapsed?
3- If we know that a patient received the antidepressant (desipramine), what is the probability that they relapsed?
4- If we know that a patient relapsed, what is the probability that they received the antidepressant (desipramine)?
